The '''LSWR X2 class''' was a class of express passenger [[4-4-0]] [[steam locomotive]]s designed for the [[London and South Western Railway]] by [[William Adams (locomotive engineer)|William Adams]]. Twenty were constructed at [[Nine Elms Locomotive Works]] between 1890 and 1892.

The class were numbered 577–596, and were an enlarged version of the [[LSWR 460 class|460 class]]. Adams had designed his {{convert|7|ft|1|in|m|3|adj=on}} drivered locomotives for the [[South West Main Line|London to Bournemouth]] route, while the {{convert|6|ft|7|in|m|3|adj=on}} drivered locomotives were intended for the [[West of England Main Line|London to Salisbury]] route which had more severe gradients.{{sfn|Russell|1991|p=172}}
